Build
For build instructions, please see the BUILD page.
Usage
C/C++
Ort::Env env = Ort::Env{ORT_LOGGING_LEVEL_ERROR, "Default"};
Ort::SessionOptions sf;
int device_id = 0;
Ort::ThrowOnError(OrtSessionOptionsAppendExecutionProvider_MiGraphX(sf, device_id));
You can check here for a specific c/c++ program.
The C API details are here.
Python
When using the Python wheel from the ONNX Runtime build with MIGraphX execution provider, it will be automatically prioritized over the default GPU or CPU execution providers. There is no need to separately register the execution provider. Python APIs details are here.
You can check here for a python script to run an model on either the CPU or MIGraphX Execution Provider.
Configuration Options
MIGraphX providers an environment variable ORT_MIGRAPHX_FP16_ENABLE to enable the FP16 mode.
Performance Tuning
For performance tuning, please see guidance on this page: ONNX Runtime Perf Tuning
When/if using onnxruntime_perf_test, use the flag -e migraphx
